I have an Endless Summer hydrangea that I planted in 2007. It did not bloom last summer nor is it blooming this summer. The plant is very healthy and is shaded. What can I do to get this to bloom?
Endless Summer is a fantastic hydrangea which blooms on both old and new wood — a plus for cold winter areas. It sometimes takes a year or two to become established, though, and it flowers best with at least four hours of sunshine a day.
If your hydrangea is growing in a shady area, it may not bloom as well as if it had a half-day of or even all day sunshine.
My own yard got shady over the last few years. It came on quite gradually, of course, so I did not notice until my two best, reliable Nikko Blues failed to bloom one year. We did some heavy pruning on a few trees and now they are blooming again.
